Difluorocarbene generated from FSO2CF2CO2SiMe3 (TFDA) at 120 °C could reacted with terminalalkynes having an ester group at the αposition to the triplebond. Difluorocyclopropenes were further converted to difluorocyclopropyl ketones under alkaline condition. Mechanism for the conversion was studied.
由FSO 2 CF 2 CO 2 SiMe 3(TFDA)在120°C下生成的二氟卡宾可以与在三键的α位具有酯基的末端炔烃反应。在碱性条件下,将二氟环丙烯进一步转化为二氟环丙基酮。研究了转化机理。
